stitchMesh, impossible to stitch two meshes

Hello everybody,
I have a very large and complex stl object of which I want to make several simulations at different z-angles but doing snappyhexmesh multiple time is very expensive. I come to the idea to split the mesh in two parts (external and internal) using a cylinder, rotate the internal mesh, merge the meshes and re do the simulation bypassing the snappy hex mesh part. However after doing the mergeMeshes command the faces are considered walls and i need to use the stitch function to connect them. Unfortunately i have this error: Code:
stitchMesh -partial -toleranceDict toleranceDict -overwrite cylinder1 cylinder2 --> FOAM FATAL ERROR: Duplicate point found in cut face. Error in the face cutting algorithm for global face 4(90670 94290 99836 97583) local face 4(1145 144 143 1146) Slave size: 6400 Master size: 8700 index: 407. Face: 6(69382 63526 66979 70500 69381 115836) Code:
stitchMesh -perfect -toleranceDict toleranceDict -overwrite cylinder1 cylinder2 --> FOAM FATAL ERROR: Points on patch sides do not match to within tolerance 1.11957e-05 I am using OF10, repo git here Github Repo with a prism to replicate the error, run with ./Allrun. Any ideas on how to solve? |
